IMPROVEMENT IN DRAG-SAWING MACHINES.

Specification forming part of Letters Patent No. 204,809, dated June 11,1878; application filed May 18, 1878.

To all whom it may concern:

Be it known that I, DAVID GATES, of Benwood, in the county of Marshalland State of West Virginia, have invented a new and useful Improvementin Grosscut Sawing Machines; and I do hereby declare that the followingis a full, clear, and exact description of the same. Z

The object of my invention is to provide an improved machine for sawinglogs into cylindrical sections of a suitable length for being worked upinto staves or stave-bolts, fencestakes, or cord-wood, &c.

The machine consists of a truck or wheeled frame, having a rotaryhorse-power gearing attached, and provided with a horizontal extension,which serves as a guide for the recip rocating cross-head, to which thesaw is detachably connected by a bolt and clevis, on which bolt thesaw-frame slides downward as the saw-cut deepens.

The invention also includes a saw-guide attached to the log and passingthrough a loop or bracket attached to the same frame;

In the accompanying drawing, forming part of this specification, Figure1 is a side elevation of my improved machine. Fig. 2 is a plan view ofthe same.

The low truck A is supported by four wheels, 13, and a sweep, G,master-wheel D, driving-shaft E, and crank-shaft F are attached thereto,as shown. The truck has, at one end, a horizontal extension, consistingof parallel grooved bars or timbers G G, between which the ribbedcross-head H is reciprocated by means of the pitman I, which connects itwith the crank of shaft F.

A long clevis, K, is attached vertically to the outer end of thecross-head H, and the sawframe L attached thereto by means of a bolt orrod, M, which passes through the bent ends of the clevis and throughlugs or arms a attached to said saw-frame.

The saw is guided in its reciprocation across the log by means of a flatbar, N, which passes through a long staple or bracket, 0, fixed on theupper part of the saw-frame. Said bar N has a forked horizontal foot,I), through which spikes are driven into the log to hold the bar fixedin a vertical position.

In practical operation, the truck A is 'set in position contiguous tothe log to be sawed into sections, and is secured there by iron stakesR, having broad perforated heads, through which pins are inserted tolock them to the wheels B, as shown. The vertical guide N is then spikedto the log, and the saw having been placed in position for beginning itsout, it is connected to the cross-head H by inserting the bolt M throughthe clevis K. The horse-power being then put in motion, the saw israpidly reciprocated with the cross-head, and as it cuts its way throughthe log it also slides down on the bolt M. Upon completion of the cutthe motion of the horse-power is arrested, the bolt M detached, and thesaw removed. The truck A is then moved along parallel to the log intoposition for another out, and the above-described steps are repeated.

\Vhat I claim is 1. The improved machine herein described, consisting ofthe truck A B, having the horizontal extension or grooved ways G G, theattached gearing, the cross-head H, clevis K, bolt M, and saw-frame L,all combined as shown and described, to operate as specified.

2. The combination of the reciprocating cross-head H, the long verticalclevis K attached thereto, the detachable bolt M, and the saw-frameprovided with perforated arms I), all as shown and described, for thepurpose specified.

3. The combination of the vertical guidebar, having a horizontal foot,by which it is secured to a log, and the saw-frame having the bracketattached thereto, as shown and described.

4. The combination of the vertical guidebar N adapted for attachment toa log, the frame having a bracket, 0, attached thereto, the long bolt M,clevis K, and reciprocating cross-head, all as shown and described, forthe purpose specified.

The above specification of my invention signed by me this 14th day ofMay, 1878.

DAVID GATES.
